Professional Video Distribution Switch Crestron CNX-PVID8x3
6 • Professional Video Distribution Switch: CNX-PVID8x3 Operations Guide - DOC. 8159A
connect independent video sources to the CNX-PVID8x3. Each connector is
supplied with RCA terminators (75 ohm). The terminators should remain attached
unless the INPUT connectors of multiple units are connected (loop-through). Refer
to "Signal Distribution to More than Eight Rooms" on page 21 for a description and
illustration about loop-through. The last unit in the loop must have terminators
installed.
All video inputs have a video sensor so that the power status of all components can
be reported. Only inputs with sync can be reliably detected (composite or
luminance).
OUTPUT (RCA Connectors)
There are three levels of eight RCA jacks (24 total) for single ended (local mode)
video.
NOTE: The information on the OUTPUT RCA connectors and OUTPUT RJ-45
connectors are identical; they are not independently controllable.
OUTPUT (RJ-45 Connectors)
There are eight RJ-45 connectors for differential video (CAT5 mode). The outputs
are grouped into three pairs and correspond to the INPUT levels as shown in the
table after this paragraph. Use a standard CAT5 cable.
